To all whom t may concem:

Be it known that I, AUGUST BoUoHERY, a citizen of the United States, residing in the borough of Brooklyn, in the county of IKingS, city and State of invented new and useful Improvements in Locks, of which the following is a speciiica- Y tion.

Vrlhis invention relates to locks in which aV keeperlixed to a door frame or door is provided with a perforated ear or ears adapted to engage in recesses in one end of al lock casing fixed to a door or door frame, and with which perforated ears tongues connected to a bolt mounted in the casing to have sliding movement in a direction longitudinal of the keeper are adapted to coperate, the said bolt being operable byV ahand ob and also by a key, and itis the object of the invention to improve the general construction of locks of this character and to' provide improved means to actuate the bolt, and to simplify andl cheapen the construction of such locks and at the same time increase the efficiency thereof.

U In the drawing accompanying` and forming a part of this speciiication Figure 1 `is a side elevation, partly in section, of' a lock showing an embodiment of my invention.

ig. 2 is a cross sectional 'view showing the same applied to a door. Y

Fig. 3 is a perspective view of the bolt; and i Fig. 4 is a perspective view of a keeper to be used in connection with the lock.

Similar characters of reference designate like parts throughout the different views of the drawing.

The embodiment of the invention shown n the drawing consists of a casing 6 having a Hanged portion 7 at the top and bottom and the rear end, the front end ofthe casa convexedly formedv portion 8, as clearly shown in Fig. 2, thus providing a casing open at-.one side which is closed by a removable bolt 9 secured to the casing by screws 10 passing through perforations' having screw threaded con- 11 in the casing with the in said bolt and nection with lugs plate adjacent its flanged portion 7 of the casing. The end portion 8 of the casing when secured to a door frame or door is adapted to extend be.

of a keeper or New York, have p Vand edges abutting against thev n yond the edge thereof, as shown in Fig. 2,

and has a recess or recesses 12 therein for the engagement of a'perforated ear or ears 13 catch plate 14. f A bolt 15 has a pair of laterally extending projections or arms slidably mounted on a pair of rods 17 fixed at their ends within the casing to permit ofthe bolt having longitudinal movement relative to the keeper and .prevent any lateral movement of the bolt.

Tongues 19 are carried by projections 18 extending opposite from the bolt to the arms 16 to extend in a plane parallel with the bolt the said tongues preferably in cross section to iit and slidably engagein the openings or perforations in the keeper ears 13. l

To impart movement to the bolt to throw the bolt tongues into and out of engagement with the perforations of the keeper ears there is provided a cam member 20 fixed to a pintle 21 rotatably mounted in the lock casing to engage between the projections 16 of the bolt. In Fig. 1 said cam is shown as engaging with vand in position to maintain the'bolt tongues out of thejperforations in the vkeeper ears, the cam-being retained in such position by a spring 22 fixed at one end to a pin 23 with the free endengaging 'with in front of stop to prevent the cam from being thrown back too far andA out of operative engagement with the upper bolt projections 16. The cam is actuated by a handknob 24 which is preferably located on the inside vof the door, and to lcause the bolt tongues to engage lin the ear perforations the knob 24 is rotated to move the cam in the direction vshown by the arrow inFig. 1 causing the cam toenbeing circular Y gage with the lower projection 16, the pins 25 during this movement tensioning and throwing the springv outward. When the .cam is moved to a position .directlyfopposite to that shown in Fig. 1 it will engage with the lower projection 16 and` maintain the bolt in such position with the bolt tongues in the ear perforations, and the cam retained in such position by the spring 20 engaging with the pins 25, a stop pin 26 preventingthe cam from being thrown out of operative engagement with the lower projection 16. It w11 1 05 l be obvious that with the,

'the perforation cam in this position the bolt tongues will be in locking position, and to throw them to unlocking` position it is only necessary to rotate the knob 24 in a direction reverse ,to the arrow.

rlhe lock is preferably operable from the outer side of the door by a key, and for this purpose there is provided ordinary key operated mechanism comprising a tumbler carrying barrel 27 in which is rotatably mounted a barrel 28 having a slot for a key 29, and having openings 2l for the engage-V ment of the tumblers'to prevent the rotation thereof, the said Ytumblers being adapted to be thrown out of said openings to permit rotation of the barrel by the key, the barrel 28 having-"means fixed thereto, as shown at 30, to connect it to the cam whereby as said barrel is rotated the key such movementV will be transmitted to the cam to throw the bolt to either looking or unlocking position.

Having thus described my invention l claim: Y
